1. Mold Construction.

Generally if you want to be inspired and create a design from scratch or modify whats available you need CAD software. There a now a plethora of choices from free opensource, FreeCAD and OpenSCAD, to brouser based and entry level software from the established market. However, the first step is that molds need to be created from stl files.

After downloading preexisting file from GrabCAD they need to be printed. To complete a whole hand there is a total of 20 files.

2x middle finger

2x index and ring finger

2x finger pads

4x thumb and thumb pads

4x base thumb joint

2x wrist joint

2x palm stability

Without having twenty pictures, the above picture shows the thumb and middle finger molds, top and bottom. These molds need to be printed in this orientation, as per the design intention.
